What Makes Ogontz's Water Unique?
Local geology and source profile
Ogontz, Pennsylvania, in Philadelphia County — a Philadelphia County neighborhood adjacent to Oak Lane and East Oak Lane in north Philadelphia — receives its water from the Philadelphia Water Department (PWD), drawing from the Wissahickon Creek and Schuylkill River (Philadelphia County) through the Philadelphia northwest distribution.
The moderately hard 153.5 mg/L hardness and TDS of 322.4 mg/L reflect the north Philadelphia PWD Wissahickon-Schuylkill blend supply's moderate character — slightly softer than the south Philadelphia Schuylkill-dominated supply (Grays Ferry: 198 mg/L) due to the Wissahickon Creek's insoluble schist input diluting the harder Schuylkill calcareous supply. The Wissahickon Creek at Philadelphia drains the Wissahickon Valley — Wissahickon Schist (slightly calcareous metamorphic — minor hardness contributor), Precambrian crystalline Piedmont (insoluble), and Triassic Stockton Formation (calcareous — primary hardness contributor at the blend ratio).
At 153.5 mg/L, Ogontz's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 7.8 ppt warrants a certified reverse osmosis drinking water filter — Naval Air Station Willow Grove (Montgomery County — AFFF), Philadelphia Naval Shipyard (legacy AFFF), and the Schuylkill River PFAS industrial corridor contribute to Ogontz's elevated readings.
Geology & Source: Ogontz in Philadelphia County draws from the Philadelphia Water Department on the Wissahickon Creek and Schuylkill River (Philadelphia County, southeast Pennsylvania) — the Wissahickon drains the Philadelphia Piedmont (Wissahickon Schist — slightly calcareous) and Triassic Stockton Formation (calcareous) — Pennsylvania Philadelphia County Wissahickon-Schuylkill Triassic calcareous watershed produces moderately hard water at 153.5 mg/L with TDS 322.4 mg/L.
